+// This module contains code that is shared between all platforms, mostly utility or fallback code.
+// This explicitly does not include code that is shared between only a few platforms,
+// such as when reusing an implementation from `unix` or `unsupported`.
+// In those cases the desired code should be included directly using the #[path] attribute,
+// not moved to this module.
+//
+// Currently `sys_common` contains a lot of code that should live in this module,
+// ideally `sys_common` would only contain platform-independent abstractions on top of `sys`.
+// Progress on this is tracked in #84187.
